2 Claims.

This application is a division of my application Serial No. 241,966,filed November 23, 1938, now Patent No. 2,247,707, dated July 1, 1941.

The invention relates to electrically operated kitchen utility devicesfor mixing, beating an extracting edible products.

The invention relates to that class of devices in which electricallydriven agitators or beaters operate in a mixing bowl mounted on aturntable so as to be freely rotatable.

One of the objects of the invention is to provide means whereby thedistance of the beater or beaters from the bowl bottom can be controlledat will, so that the beater or beaters will have the optimum effect uponthe particular material being treated.

Another object is to provide a turntable support in a device of thisclass which can be maintained under a nice control so far as heightadjustment of the turntable with respect to the beater is concerned.

Another object is to prevent the turntablereceiving socket, after oncebeing adjusted for height, from being jarred or otherwise inadvertentlydislodged or shifted from its adjustment.

To these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

In the accompanying drawing:

Fig. l is a side elevation of a kitchen utility device embodying myimprovements, showing a large mixing bowl in position on the turntable;

Fig. 2 is a detail bottom view of a portion of the base showing themixing bowl adjusting means; and

Fig. 3 is a section on line 3--3 of Fig. 1.

In general the type of kitchen utility device illustratedis well known.This device comprises a base, indicated generally at A, a pedestal B, amotor member C overhanging the base, and depending agitators or beatersD. On the base A is a rotary turntable E adapted to support a mixingbowl F in which the beaters operate. The motor member has a detachableconnection with a bracket G at the upper end of the pedestal, and isprovided with a handle C' by means of which it can be held by the handof the operator when detached from its support.

The base A is equipped with two socket members 5 and 6, either of whichis intended to support a mixing bowl rotatably through the medium of theturntable E. When the latter is mounted in the member 5, the bowl F,which is a large bowl, will be located relatively to the agitators D inthe manner indicated in Fig. 1, it

being noted that in this particular instance one agitator is arranged inadvance of the other, the shafts of the agitators being disposed in aplane slightly offset from and substantially parallel to a verticalplane passing lengthwise through the motor member at the center thereof.Other arrangements can, however, be adopted Without in any manneraffecting the subject matter of the present invention. In this casesocket member 5 is in line with the vertical center plane of the motormember, which plane also passes through the center of pedestal B, butthis also is not essential. The socket member 6 is somewhat 011- setwith respect to socket member 5 and closer to the pedestal, and enablesa smaller bowl (not shown) to be mounted on the turntable to cooperateoperatively with the agitators.

The socket members 5 and 6 are mounted in the base A for verticaladjustment in the manner shown in Figs. 2 and 3. Each socket member isof cup-shaped formation having a closed bottom portion 1 and an upperlateral flange or rim 8. The outer surface of the socket member body isprovided with screw threads 9 engaging a tapped hole II] in the upperwall I l of the base member, so as to be capable of being screwedupwardly and downwardly therein. The bottom portion of the socket memberis surrounded by a washer l2 clinched in an annular groove and acting asa stop which abuts shoulder [3 to limit upward adjustment of the socketmember, whereas downward movement of the socket member is limited by theflange 8 coming in contact with the upper surface of the base. Thesocket member has a socket M in the bottom of which is clinched ananti-friction ball l5 adapted to support from below a swiveling pin 16carried by the turntable E and introduced into the socket member. Theswiveling pin I6 is non-rotatably connected as by riveting to the sheetmetal turntable body, as indicated at H, and the exterior side surfaceof the pin l6 engages the inner surface of socket I4, while the lowerreduced end of pin I6 rests on the ball l5. In this manner the turntableis mounted for Very free rotation in the socket member, although tippingis effectively prevented.

For convenience in turning each socket member manually from the upperpart of the base for the purpose of raising and lowering it, the sidesurface of flange 8 is roughened as by knurling.

For the purpose of preventing the readily turnable socket member whenadjusted from being shifted out of its adjustment by the slightvibration of the machine, or otherwise, I have provided means forpreventing angular movea ball [9 adapted to be pressed into any one ofthese grooves. In the particular form shown,

where there are two socket members, a helical spring 20 is common totwo'balls I9, being interposed between them as shown in Fig. 2', so asto press one ball into a groove of one socket mem-- her, and the otherball into a groove of the other member.

groove 2| at the under portion of the base, and is held in place in saidgroove by a cap plate 22, which in turn is held in place by a screw 23.It will be noted that by this arrangement'the ball has a strong tendencyto arrest rotation of the socket member every time it engages a groove.In this particular case it engages a groove at each quarter revolutionof the socket member. her, when once adjusted to give the propervertical adjustment to the turntable and ball with respect to the beateror beaters, will not readily come out of adjustment.

For the optimum efiect of the beater or heaters upon the materialundergoing treatment, it is important that there be a nice adjustment ofthe distance of the beater from the bowl bottom, and it is also quiteimportant that the adjustment when once made be maintained so long asthe particular operation is being carried on. By my invention theseimproved results are brought about in an efiective manner. Nevertheless,the means for adjusting and maintaining" the adjustment of the socketmember is of simple form and relatively inexpensive.

While I have shown a preferred form of the turntable mounting, it is tobe understood that the invention can take other forms, and that Toenable this to be accomplished the spring 20 is arranged in a curved Bythis arrangement the socket mem-,

above and-rotatably mounted with respect to a suitable base, a mountingfor the turntable intended to receive a pin carried by and extendingdownwardly'from the turntable, constructed to permit adjustment of theturntable height by manual manipulation from the top of the base and tomaintainthe adjustment against the effect of jarring and vibration, saidmounting comprising a socket member open at the top receiving themounting pin of the turntable and provided above the base and beneaththe turntable with a lateral manipulating flange, said socket memberhaving on the body thereof exterior threads engaging threads in the basestruc ture so that by turning said flange said socket member can bevertically adjusted relatively to the base, said flange being adapted toengage the upper surface of the base in order to limit the downwardmovement of the socket membenthe threads on the socket member beinginterrupted at intervals by substantially upright grooves, and a-springpressed detent device movable laterally in the base structure at oneside of said socket member adapted to engage said grooves successivelyas the socket member is turned and acting to prevent any substantialvertical dislocation of the socket member under the eiTects of jarringor vibration.

2. A. kitchen utility devicesuch as set forth in claimi'l', in which thesocket member is provided exteriorly adjacent the lower end with aninset stop washer engageable with the under surface of the base to limitthe upward movement of the socket member.
